<h1>Mesa 20.0.3 Release Notes / 2020-04-01</h1>

<p>
    Mesa 20.0.3 is a bug fix release which fixes bugs found since the 20.0.2 release.
</p>
<p>
Mesa 20.0.3 implements the OpenGL 4.6 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 4.6. OpenGL
4.6 is <strong>only</strong> available if requested at context creation.
Compatibility contexts may report a lower version depending on each driver.
</p>
<p>
Mesa 20.0.3 implements the Vulkan 1.2 API, but the version reported by
the apiVersion property of the VkPhysicalDeviceProperties struct
depends on the particular driver being used.
